IMPROVEMENT IN BOOK-CLAMPS.

Specilication forming part ol' Letters Patent No. 148,249, dated March3, 1874; application filed December 29, 1873.

To all whom 'it may concern:

Be it known that I, DAVID SEAWRIGHT, of Pittsburg, in the county ofAllegheny and tate of Pennsylvania, have invented a new and usefulImprovement in Book-Clamps; and I do hereby declare the following to bea full, clear, and exact description thereof, reference being had to theaccompanying drawing` Inaking a part of this specification, in which-Figure l is a side elevation of my improvement, and illustrates themethod of carrying a book. Fig. 2 is an edge View, and Fig. 3 is asectional View, of thel box containing the pencil-case.

My invention consists ot' a book-carrier, in which the sides are securedto each other by means ot' adjustable elastic bands fastened byfriction-buckles.

To enable others skilled in the art to make and use my invention7 I willdescribe its construction and manner of use.

0n the upper end ofthe side a', and on both ends ot' the side a., is apiVoted friction clasp or buckle, d, and pressing upon the same aspring, c, which holds said clasp down against the face of the sides aa. At the upper end ofthe holder the band e is passed through and:

under the friction-clasps (l.V It may be inserted by drawing back thesprings c and then slipping it through' the clasps. This band, beingheld simply by the friction of the buckle, may be adjusted to form aholder of diii'erent widths. Upon the lower end of the side a there is ahook, y, which is arranged opposite to the clasp on the lower end of theside a. The band lL is passed through the clasp on the lower end of theside a, in the saine manner as has been described with reference to theband e, having a looped end, which may be drawn across and slipped outhe hook g. This band maybe lengthened and shortened, in the mannerdescribed with reference to the band e.' Attached to the lower end ofeach pie-ce a a is a stay or stop, k, to

afford a more extended bearing-surface for the books which arev in theholder. The ends of these stays are bent inward. The holder is providedwith a handle, t', which is secured by the cords i.

This holder is used as follows: The hands being adjusted to the properwidth with reference to the books to be carried, the books are, placedin it, and the lower strap is drawn across and looped upon the hook. Incase the weight of the books carried is great, their tenl dency is tofall out cornerwise.4 This I prevent by means of the stays k, the bentends of which extend under the projecting edges of the books and preventtheir tipping either way.

One great advantage of this holder is that the carrying-strap is at theend. In most of those in use it is at the side. The latter is verytroublesome' and inconvenient, because the corners of the books strikeagainst the person carrying.

In connection with this holder, I have formed a box, m, upon one of thesides a. This box is for the purpose of containing pencils and otherarticles of like nature.

My improvement is a convenient, easily-adjusted, and greatly-superiorholder.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. The combination of the sides a a', the friction-clasps d, springs c,bands c h, and hook `g, the whole forming a clamp for carrying books, asdescribed. i

2. In combination with the clamp, formed by the sides a a with theiradjustable lendfastenings, the stays k, for the purposes described.

In testimony whereof, I, the said DAVID SEAWRIGHT, have hereunto set myhand.

DAVID SEAWRIGHT.
